cinema DNG metadata isn’t fully supported in premiere. it also force interprets it into rec. 709. 3:1 compression isn’t supported at all. sequence import isn’t supported as well.
premiere won’t color manage P3 unless its jpeg2000. it will interpret everything into rec. 709. you would need a monitor that supports loading LUTs or a special transform LUTs.
opengl isn’t supported in premiere so only quadro cards or blackmagic will output 10 bit. the new 1080gtx will only preview 8 bit. the older quadro cards are incompatible with cc 2015.
to run 6k full will require a new 8 core I-7 i7-6900k overlocked to 4.2GHZ with 64GB Ram, 2500MB/sec hard disk speed for multiple layers. Even 6k compressed Redcode is 244MB/sec per clip. thunderbolt sas/raid/backup etc.
resolve will require use several graphics cards with 8GB RAM.
if you don’t plan on spending at least 2-3 grand on a computer, I suggest looking at the proxy workflows. It will take much, much longer to transcode though.
